I was indeed playing on a 4k monitor. Playing with my resolution gave me some relief, but by default it was not at a terribly practical scale.
I will say I enjoyed what you have going so far, all UI issues aside.
Please do something about text scaling for higher resolution screens in future updates. If the entire UI is a command line the text truly does need to be sized so that you can read it.
Any guidance on getting the MacOS version to work? I just get a "The application 'Pixelgrab.app' can't be opened" popup when I try to open the app..
I'm on a new M2 MacBook Pro running Ventura 13.4.1
